Abstract

Communal land restoration programs in Ethiopia overlooked the socio-economic context and decision behavior of smallholder farmers for better planning and intervention. Thus, studies related to socio-economic aspects and decision behaviors of smallholder farmers prior to the implementation of communal degraded land restoration are scanty. This study assessed the socio-economic characteristics and decisions making of smallholder farmers in degraded communal land restoration. The kebele under study was purposively selected near the communal degraded land for future intervention. Cross-sectional data were collected from 94 smallholder farmers selected using a systematic random sampling method. Binary logit was employed to see determinants of farmers’ decision to participate in the rehabilitation of communal degraded land. The study result revealed that attitude towards village leaders and labor availability positively determines farmers’ decision, while credit to access and absence of local institutions negatively influence the willingness of farmers to participate in communal land restoration. It seems that the socio-economic base of smallholder farmers did not have a strong linkage for their decision in the land restoration effort. The findings generally suggest that there should be locally based capacity building of the community in a participatory approach for land restoration efforts.

Abstract

This study aimed to determine the appropriate dose of dolomite, dose of K fertilizer, and the interaction of the treatments on the growth and yield of cucumber on peat soil soil. This research was conducted in Medan Baru, Muara Bangka Hulu Sub-district, Bengkulu City at an altitude of ± 10 meters above sea levelfrom September to December 2021. The experiment method used was a factorial Randomized Complete Block Design (RCBD) consisting of two factors; first, dose of dolomite with 3 levels consisting of 0.00 tons ha-1, 1.25 tons ha-1, and 2.5 tons ha-1 Dolomite, and the second, dose of potassium fertilizer consisting of 4 levels; 0 kg ha-1, 200 kg ha-1, 400 kg ha-1, and 600 kg ha-1 with 3 replications. Each unit of the experiment pot was planted with 3 plants therefore whole samples were obtained 108 experimental plant units (polybags). Cucumber growth and yield significantly responded to the dolomite and potassium application. The interaction between the dolomite and the potassium applied significantly to the cucumber planted shown by plant length, the diameter, and length of the fruit.

Abstract

The need for soybean commodities is increasing in line with increasing changes in population and public awareness of the importance of food nutrition. One of the efforts to increase soybean production is to improve crop cultivation by selecting superior varieties. The purpose of this study was to obtain soybean varieties that had the best growth response and yields by adding dolomite to a saturated soil culture (SSC). This research was carried out from November 2020 to February 2021 in the experimental land of the Department of Agricultural Cultivation, Faculty of Agriculture, University of Bengkulu. The design used was a randomized completely block design (RCBD) factorial pattern consisting of two factors. The first factor was the dolomite dose which consisted of 4 levels, namely 0 x Al-dd, 0.5 x Al-dd, 1 x Al-dd, and 1.5 x Al-dd. The second factor was soybean varieties consisting of Gepak Kuning, Dering 1, and Derap 1 varieties. The results showed that Gepak Kuning produced the best growth response and yield by adding dolomite to SSC.

Abstract

Soil moisture prediction models on a regional scale can be developed by looking for the relationship between water balance and basic soil properties such as texture and organic matter.  Our previous research has obtained soil dielectric properties measurement technology as an estimator of soil moisture that can be done quickly in the field. The purpose of this study was to apply this technology in estimating the characteristics of soil moisture insitu in the field on a district scale in Bengkulu Province.  The research was conducted for three years in three different districts in Bengkulu Province. The results of the third year to early October 2021 study showed that land under thicket stands and oil palm had higher weekly groundwater fluctuations than under rubber. The highest impedace of groundwater below the thickets and palms are present at depths of 0-20 cm and 0-10 cm, respectively.  However thickets have fluctuations in the depth of total groundwater (0-30 cm depth) that are higher than those of oil palms during three months of measurement.  In contrast, the soil moisture content profile under the rubber stand is relatively more stable against the influence of weekly rainfall during the measurement. An analysis of the relationship between non-free variables (field capacity moisture content, permanent wilting point and water available) and free variables (sand, dust, clay and C-organic) will be carried out in November 2021

Abstract

Entisols are soils that are widely used in Indonesia, both for irrigated and rainfed rice fields, for vegetable cultivation, and others. Vermicompost also contains many of the nutrients available to plants and increases soil porosity, soil aeration, and humidity, and controls soil erosion so that it can help in buffering toxins for plants and promoting plant growth. Corn is a cereal crop that is the second most important food crop in Indonesia besides rice. The volume of corn imports is higher than exports, this is due to the high demand for corn but domestic corn production has not been able to fulfill it. The experimental design used was a Randomized Completely Block Design (RCBD), seven levels of vermicompost doses, namely 0; 2.5; 5.0; 7.5; 10; 12.5; and 15 tons ha-1) each repeated 4 times. This study aims to determine the dose of vermicompost fertilizer that can improve the properties of Entisols and yields of maize (Zea mays L.). The application of vermicompost fertilizer with seven dose levels had a significant effect on N nutrient levels in coastal Entisols. Doses of vermicompost were able to increase dry stover weight, cob weight with husk, and cob weight without husk of corn plants.

Abstract

This study aims to study the effect of land slope and distance from the main crops on soil water content at the end of the rainy season. The research location is located at position 3°41'51.8"S - 102°18'58.0"East in Talang Tengah I Village, Pondok Kubang District, Central Bengkulu. The research was conducted in February - April 2021. Soil analysis was done at the Soil Laboratory, University of Bengkulu. The study used a completely randomized block design with two factors. The first factor is the slope of 0-3% and 30%. The second factor is the distance of the cutting slope from the main oil palm tree, namely 1.5; 2.0; 2.5; 3.0; 3.5; and 4.0 m. Data were analyzed using ANAVA and LSD at 5% level. The results showed that the slope of the land and the distance between the slopes had a significant effect on the soil water content. The soil water content in both gravimetric and volumetric methods on slopes of 0-3% is higher than on slopes > 30%. The water content at a distance of 1.5 to 3 m from the tree of oil palm is lower than at a distance of 3.5 – 4.0 m.

Abstract

Improvement of Ultisol soil chemical properties can be done by adding organic matter. In this study, vermicompost was used from various animal wastes (chickens, goats and cows), and the optimal growth parameters and nutrient uptake were observed. Research results showed The chicken manure vermicompost had the maximum available P, the goat manure vermicompost had the highest available K, and cow manure vermicompost had the highest total N value. In terms of pH, goat manure vermicompost had the highest pH and the chicken manure vermicompost had the most excellent C/N ratio. Analysis of variance (Anova) showed that the type and dosage of vermicompost had a significant effect on growth parameters (plant height, number of leaves and stem width) and nutrient uptake of N, P and K
